Are all your products vegan?

Yes, all of our products (and the two of us!) are 100% vegan and cruelty free.


Are all your products palm-oil-free?

Yes, we do not use any form of palm oil in our products. If you want to read more about it check out our blog post on palm oil here.


Do you manufacture everything you sell?

All of our products are handmade by us in our small workshop in Cambridge (UK) using a 100% renewable energy supplier and with the help of a small amazing team! We are a certified real living wage employer.


What is the difference between the saponified shampoo bars and the 2in1 solid shampoos?

Saponified shampoo bars are produced using the traditional cold process method, using fully natural ingredients, to create a bar that is similar to a soap bar, with moisturising properties that make it great for your hair. Natural shampoo bars have an alkaline PH of 8, which makes them milder than other equivalent products, but given its slightly alkaline PH, it will need the use of an acid rinse to balance out the PH of your scalp after washing your hair.

On the other hand, 2in1 solid shampoos follow a different production method based on the use of two gentle, natural-derived surfactants, Sodium Cocoyl Isethionate and Cocamidopropyl Betaine. 2in1 solid shampoos have a balanced PH of 5.5, making them extremely gentle on your scalp. For this reason, they will not need an acid rinse.


Do I need a conditioner after using your shampoo bars? 

No, conditioner is not needed after using either of our shampoo bars! When using our natural shampoo bars, we highly suggest to use an Acid rinse (which helps rebalance the PH and leaves the hair detangled and shiny).

If after a few weeks of using our natural shampoo bars, you were to find that your hair need some conditioning properties we suggest making a hair mask with natural oils/butter to apply on your damp hair prior to showering, alternatively you can use our organic face+hair Bliss Beauty Oil (which is what I, Bianca, use).

Will you ever make a conditioner bar?

This is definitely one of the questions we receive most often haha. But no, we don't currently have plans to make a solid conditioner as we have never found a formulations or solid conditioner that we truly liked, for this reason we make sure to ensure that all of our shampoos have some conditioning agents as well, so that most people won't need to use a separate conditioner!

Our natural shampoo bars contain ~5% of unsaponified oils in addition to the naturally occurring vegetable glycerin (a byproduct of the saponification process), which both act as moisturising agents, while our 2in1 solid shampoo contains conditioning ingredients, so that you won’t need to buy both a shampoo and a conditioner!

We have also created  a multipurpose face+hair moisturiser, the Bliss Beauty Oil, which can be used after the shower on damp hair!


How do I make an acid rinse?

We have a full guide with all the information on how to make and use an acid rinse here!


My hair get greasy after using a natural saponified shampoo bar, what should I do? 

When switching from conventional shampoo to a natural saponified shampoo bar you may go through the so-called "transition period", which will usually last 2-3 weeks during which your hair may get oily faster. As this is an adaptation period you should refrain from washing your hair more often.

Not everyone goes through a transition phase and this depends a lot both on the hair type, the water hardness and the type of products used before moving to a shampoo bar!

Once the transition phase is over you will find that your hair is lighter and softer, and thanks to the Acid Rinse they will also remain shiny!

For more information on using natural shampoo bar and on the transition period check out our free guide!


Do the 2in1 shampoo+conditioner bars require an acid rinse or a transition phase?

No, the 2in1 line was created for all those people that don't get on with saponified shampoos or for those that have coloured hair. All of the products in this line are PH balanced, don't require an acid rinse and don't have a transition phase, this means that they can be used in hard water areas!


I have coloured hair, which shampoo should I use?

For coloured hair we suggest choosing one of our 2in1 shampoos, these shampoos won't strip colour from your hair and they all contain hydrolysed quinoa protein, a vegan protein that, in addition to improving shine and combability, help with colour retention.


Why aren't the products 100% organic?

We thought a lot about whether making our products organic or not, and we came to the conclusion that, at the moment, this is not economically feasible. In fact, if we made all of our products 100% organic the price would be much higher.

Nonetheless, whenever the price difference is small, we do choose organic options, and that is why all of our products have at least some organic ingredients. 


What is the difference between a handmade and a commercial soap?

During the saponification process, glycerine is produced. In industrial soaps, glycerine is normally extracted and sold or used in other cosmetic products. Handmade soaps do instead contain naturally occurring glycerine and therefore are a lot more hydrating.

Also, a lot of commercial soaps use synthetic fragrances and ingredients which can be harmful both to the body and the environment.


Can your soap bars be used as shaving soap?

Yes, most of our soap bars (Aloe Vera Soap, Shea Butter Soap and Red Clay Soap) create a very soft lather which allows them to be used as shaving soap. Alternatively, you can also use any of our saponified shampoo bars!

You can create the lather with your hands or use a shaving brush to create even more bubbles, both ways work amazingly!


Can I use your products while pregnant?

If pregnant or nursing we suggest contacting your doctor and ask information about what products are safe for you to use as some essential oils are not considered safe to use while pregnant.


How do I take care of the soap and shampoo bars to make them last longer?

It is very important, after using soap and shampoo bars, to ensure that they dry very well. Soap and shampoo bars should be kept on a draining soap rack, and in a dry environment.


Is the packaging compostable?

All of our boxes are 100% compostable, but recycling would be a better option as it extends the life of the material!

Unfortunately, we were not able to find a provider of compostable sticky labels that accepts small orders, therefore our deodorant, balms and beauty oil labels use a synthetic glue, and hence, are not compostable. However, they are printed on unbleached paper!


Are the deodorants antiperspirant? 

No, they are not antiperspirant. Our deodorants will prevent bad smells due to their antibacterial power, but will not prevent sweat. Sweating is a natural body activity used to expel toxins, for this reason, it is not suggested to prevent it through the use of antiperspirants.


Can I return the deodorant/balm tin to be reused?

If you live in Amsterdam or are willing to cover the shipping costs we accept returns on our deodorant and balm tins in exchange of a €0.50 discount code on your next order.

Please note that if you return more than one tin, the various €0.50 discounts can be combined. Just let us know if you wish to have separate discounts or a cumulative one and provide an email address where to send the discount code in the parcel.

You can ship the to the following address: Zero Waste Path EU B.V., H.J.E. Wenckebachweg 144-148, Unit B.3.3, 1114AD Amsterdam, the Netherlands


My deodorant has melted, what can I do?

Sometimes during transport the deodorant can melt a little due to the very high temperatures inside the postal/courier vans, in this case we suggest giving the deodorant a mix and putting it in the fridge for a couple of hours to solidify again. It can then be kept outside the fridge even in very warm weathers, as long as it's not under direct heat/sun.


How do I use your Lotion bars?

To use our lotion bars, simply rub the bar on your damp skin after showering, and then massage the oils with our hands to spread them around! Make sure not to use a lot of it, the bar is made only of candelillla wax and 100% natural oils, so a little goes a long way!



How can I modify an order?

If your order hasn't been shipped yet, you can modify it by sending us an email at Remember to include the Order number and which products you would like to add or delete from the order. If you have added products to the order you will receive an automatic email that will allow you to safely pay online for the additional products. 


How can I cancel an order?

An order can be cancelled only before it has been shipped, to do so, send us an email at, and we will refund the order for you. Remember to include your order number in the email!



Where do you ship to?

We ship to all of Europe except the UK, to order from the UK head to our British website. Please note that non-EU countries may require you to pay custom duties.

We have decided not to ship outside of Europe as we don't feel comfortable with the high emissions deriving from such long-distance freight. That said, if you live in a country where you don't have access to zero waste options we are more than happy to make an exception and ship to you, just contact us before ordering to arrange it!

Complete list of the countries we ship to:

If you want to check our Shipping Policy and prices you can find it here!


Why don't you ship outside of Europe?

We have decided not to ship outside of Europe due to the air miles and consequent carbon emissions that wold be involved in doing so. We feel that we should encourage people to buy locally, both to support the small producers that live in their area and to reduce the carbon footprint of their shopping.

If you live in a non-European country that doesn't have access to this type of products though, we'd be happy to make an exception for you! We don't want our "rule" about shipping and emissions to make it even harder to find zero waste products for people that can't find them locally!


My order has not arrived, what should I do?

Delivery times are indicative, and are normally not guaranteed. However, if you order has not arrived by the standard shipping time, do send us an email! 

We are always looking for more efficient and effective shipping option, so hopefully in the future we will be able to improve this.


Is your shipping also plastic-free?

All of our products and shipping packaging are 100% plastic-free, recyclable and often recycled.

Because we also reuse all of the shipping packagings we receive, you may sometimes receive a package that contains plastic. However, as we know that some people don’t like receiving plastic in their mail, you will find an option during check-out asking whether you are okay with us using reused packaging materials. We ask our suppliers to ship 100% plastic-free, but this isn't always possible.


Are the shipping costs calculated automatically?

Yes, the shipping costs are calculated automatically at the check-out based on the total weight of your order and your destination.


The company

Are your products safe?

All of our products have been assessed for safety in compliance with Annex I, EC Regulation 1223/2009 (EU Law).

Even though we are a small business, this doesn't mean that we don't do everything legally! We are a registered business here in the Netherlands, and all of our products are registered in the EU Cosmetic Product Notification Portal.

All of our labels are in compliance with EU legal requirements, meaning:

- Ingredients are listed using INCI names

- Name of the product

- Address of the company

- Batch number

- PAO (period after opening)/BBE (best before end) information


What is the difference between you and a conventional company?

The main difference between us and most conventional companies is that not only we package and ship completely plastic-free and reuse all the packagings we receive, but we also put an extra effort in reducing waste (and in particular plastic) in the production stage. We share all the information about the waste we produce as a company in the  section of our website and on our social media accounts.

Also, we will spend our profits in environmentally conscious ways as we try to be zero waste and sustainable also in our everyday lives, in addition to being both vegan.


Are you committed to be palm-oil-free? Why?

Yes, when we started making our products we decided to commit to being 100% palm-oil-free. While Palm oil can be very useful in soapmaking, as it lowers the costs and gives extra hardness, we decided to exclude it completely in our recipes, substituting it with larger amounts of shea and cocoa butter.

To read more about the reasons behind this choice check out our dedicated blog post!


But why didn't you choose to use Sustainable Palm Oil like other companies did?

Even if we believe in the seriousness of some of these certifications, we do think that the over-consumption of one specific ingredient is never really sustainable. And the consumption of palm oil/sustainable palm oil is still very high among companies.

In addition while it can be hard to eliminate completely palm oil from some products, it's fairly easy to avoid it in cosmetic products, and we believe that eliminating it where it's not needed will allow for a more balanced demand, that will be able to be fulfilled by those that produce it sustainably.
